SPECIFICATION forming part of Letters Patent No. 783,588, dated February 5%, 1965.

Application filed January 24, 1898. Elcrial No. 667,732,

To (0717/ who/It it In/my (so/worn:

Be it known that 1, Moses 0. N men, a citizen ot' the United States of America, residing at 412 East Berry street, Fort Wayne, Indiana, have invented certain new and useful .l.mprovements in Baling-Presses; and l do doclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specilication.

The invention relates to that class of balingpresses known as perpetual, in which a reciprocating plunger is employed in which there are separate feed and discharge apertures and which is provided with a feeder for torcing the material into the compressionchamber.

The objects of the invention are to simplify, and consequently cheapen, the construction and to increase the general e'liiciency of the machine; and it consists in the various parts and arrangement o'l parts, as hereinafter fully set forth.

In the drawings, Figure 1 is a side elevation oi a baling-press. Fig. 9. is a plan view of the same, some of the parts being broken away. Figs. 8 and 4. are details of the pitman for driving the plunger. Fig. 5 is a detail of the plunger, and Fig. 6 is a detail of the clutchoperating mechanism.

The body or case of the press is designated A and is shown as being mounted upon a runhing-gear, as is common in this type ol. machines. l he plunger shown at B, the teeding-platt'orm at C, and a condensing mechanism for gathering the charge into a reduced mass over the feed-aperture is shown at I).

At E is shown a d rive-rmlley, which in this case constitutes also a balance-wheel, this pulley being mounted upon a shaft c, journaled in suitable boxes mounted upon the frame A. Power is transmitted from the shaft 0 by means of a geared pinion F inter-meshing with a gear-wheel Gr, mounted upon a shaft 7, journaled in brackets g, rising from the top of the fame A. A pair or scroll-gears H, being modifications of an involute curve,

are mounted upon the shalt r one near each side of the frame A, and these gears intermesh with a similar pair of gears if, mounted upon the stud-sl'iatts k. projecting inwardly from the side walls of the frame A. A wristpin L is carried by the gears K hi, having its ends set one in each of said gears. A pitman M connects the wrist-pin l; to the plum ger B.

An oscillating feeder U, playing in and out of the teed-aperture oi the compressioii-chamber within the frame A, is carried by a leverarm 0, which may be pivoted upon the shaft r and the power-receiving end of this arm is curved to give proper movermnit and longitudinally slotted to receive and ride upon the wrist-pin L, the end oi the pitman M being bifurcated tor its accommodation. The leeder O is pivoted to the lever-arm o, and its oscillation upon such pivot is controlled by a jointed arm o, connecting its upper end with the bracket 7 back ot the shal t g. in earlier patents I. have shown similar scroll-gears and a somewhat similar arrangement ol. Feeder, as well as the same form of condensing mechanism, as are illustrated in this application. The novelty in the present construction, however, resides in part inthe use of two pairs ol thescroll-gears and of a wrist'pin llXUll between the members of one pair and taking the place of the crank shown in the said earlier patents, No. 575,660 and No. 372,636. A further improvement on the old construction is shown in the peculiar manner of mounting and actuating the lever-arm ol the feeder, as above described, whereby l am able to con siderabl y shorten the machine and increase its length by makingit more compact. The pitman Al is also of novel mmstruetion, its body portion being composed of a pair of channelirons P P, secured together back to back, their rearward or crank ends being spread apart, as plainly shown in Figs. 2 and Z in order to accommodate the lever-arm o. A journalbox Q'l or engaging the wrist-pin L is secured to the rearward end of each of the channelirons, and a cap 1 cooperates with each box and is held in place by a strap it, looped over it and having its ends securely bolted to the flanges p of the channel-iron. Set or pressure screws "1" 9" pass through the loop of the strap R, so as to bear upon the back of the cap q, whereby its adjustment to the boX Q may be regulated. The shank of the box Q may be provided with transverse ribs or bosses 1', longitudinally drilled to receive the bolts by means of which the strap R is secured to the flanges pp of the channel-iron P. A further advantage in spreading the two members P P of the pitman at its rearward end is found in the fact that the strain is thereby transferred from the middle portion of the wristpin L nearer to its ends.

The forward end of the pitman isprovided with a suitable apertured connecting-block Q, by means of which it is pivotally attached to the plunger. I have furtherimproved the press by interposing between the balance wheel E and the transmitting-gears of the press a clutch S. This is preferably accomplished by mounting the gear-wheel F loose upon the shaft 0 and employing any suitable form of clutch (indicated at S) for engaging it with the shaft. This clutchis controlled by hand-levers S S, rising one at each side of the feeding-table C, so as to be in convenient reach of the operator when working at either side of the machine, and these hand levers are connected with the clutch by means of a crossbar a bell-crank s connectingrods .9, and a second bell-crak .9, directly engaging the clutch mechanism.

The plunger B is provided at its top with a movable plate T, as is common in machines of this kind. Ihave improved upon the construction of these devices by pivoting the plate to the top of the plunger at its rearward end and providing it with a downwardly-depending arm 2f, between the end of which and a portion of the plunger is located an expansion-spring t, which tends to throw the forward end of the plate T upwardly.

A further improvement consists in a special form of division-block inserter shown, which comprises the parallel arms V; each having a longitudinal groove or channel in its inner face, these arms being carried by a pair of lateral arms 11, secured together and pivoted, by means of the rod 1/, to a pair of lugs which may be formed upon the framework (Z of the condensing mechanism D, the length of the arms a being such that the inserter may be thrown over so that its channeled arms V will be over the feed-aperture of the compressionehamloer. The arms V are spaced apart a distance equal to the width of the divisionblock used in connection with the machine, so that the block may be inserted into their channels and carried over into the compression-chamber. The feeder O is provided with a lateral lug 0, adapted to bear upon the upper end of the division-block so as to dislodge it from the inserter.

The operation of the machine is as follows: A charge of hay having been condensed in the condensing mechanism D is forced into the compression-chamber by the descent of the feeder O as the plunger B recedes, the rearward end of the lever-arm 0 being raised by the crank-pin L during the recession of the plunger. At the end of the back stroke of the plunger those portions of the scroll-gears in which the radius is most rapidly gradually changed is reached, and the advance movement of the plunger is made at a rapidly-decreasing speed, so that at the time of greatest resistance a maximum of power is attained. As the pitman reaches the center at the end of the instroke the scroll-gears pass the step at which their radii are abruptly changed, and the recession of the plunger is made at high speed. As the bale in the process of compression nears completion a division-board is inserted between the arms V of the inserter, and at the completion of the bale the inserter is overturned, so as to drop the division-board into the compression-chamber. This is done, of course, as the plunger recedes and before the feeder O has entered the chamber. Should the division-board not fall freely, the lateral lug 0 comes into contact with its upper edge and forces it downwardly. The machine is controlled by the operator by means of the levers S S, it being immaterial upon which side of the machine the operator stands.

I claim as my invention 1. In a baling-press the combination with a frame, stud-shafts standing in from each side of the frame and being in axial alinement, a driving-wheel mounted upon each shaft, a wrist-pin set in the two wheels, of a compressing-plunger, a pitman connecting the wristpin with the plunger and having its end connected with the wrist-pin forked, an oscillating feeder, a lever-arm carrying such feeder and having its end slotted and engaging the wrist-pin between the two branches or forks of the pitman.
